Weekly carbonate chemistry condition data recorded between 2008 and 2014 in the Chuuk lagoon (7.3°N and 151.5°E) of the Federated States of Micronesia, located in the western...

The properties of the heliospheric magnetic field and the solar wind were substantially different in the unusual solar minimum between Cycles 23 and 24: the magnetic-field...

Seasonally and vertically resolved changes in the strength of the Brewer-Dobson circulation (BDC) were inferred using temperatures measured by the Microwave Sounding Unit (MSU),...

In this study, equatorial electrojets (EEJs) simulated by the Thermosphere-Ionosphere Electrodynamics General Circulation Model (TIE-GCM) were compared with those observed by...

Formation and growth of ultrafine particles is crudely represented in chemistry-climate models, contributing to uncertainties in aerosol composition, size distribution, and...

A nondeveloping tropical disturbance, identified as TCS025, was observed during three intensive observing periods during The Observing System Research and Predictability...

Recent optical observations of aerosols in the upper stratosphere and mesosphere show significant amounts of extinction at altitudes above about 40 km where the stratospheric...

This paper describes a quasi-operational regional air quality forecasting system for the contiguous United States (CONUS) developed at the National Center for Atmospheric...

The evolution of a heavy rainfall event that occurred on 19 August 2014 in northern Taiwan is investigated using observed data and analyzed using a newly developed system,...

Based upon on the findings of Y. Li and R. E. Carbone, the association of tropical rainfall with SST structure is further explored, with emphasis on the MJO passband. Analyses...

This summer the Boulder science community is commemorating the anniversaries of several key historical events in solar physics and space weather. Seventy-five years ago in 1940...

The Parker Solar Probe (PSP) and Solar Orbiter missions are designed to make groundbreaking observations of the Sun and interplanetary space within this decade. We show that a...

Recent work suggests that natural variability has played a significant role in the increase of Antarctic sea ice extent during 1979-2013. The ice extent has responded strongly...

Airborne radar analysis of a mesovortex that developed near the apex of a bow echo is presented. The mesovortex was shown to play a critical role in determining the location of...

Long-term variability and tendencies in migrating diurnal tide (DW1) are investigated for the first time using a three-member ensemble of historical simulations by NCAR's Whole...

Understanding why animal societies take on the form that they do has benefited from insights gained by applying social network analysis to patterns of individual associations....

In this study w e explored why the different initial tropical cyclone structures can result in different steady-state maximum intensities in model simulations with the same...

Ultraviolet (UV) actinic fluxes measured with two Scanning Actinic Flux Spectroradiometers (SAFS) aboard the NASA DC-8 aircraft are compared with the Tropo- spheric Ultraviolet-...

In a recent study, the authors performed numerical simulations of conditionally unstable flows past a mesoscale mountain ridge in order to investigate the statistically...

The Regional Arctic System Model version 1 (RASM1) has been developed to provide high-resolution simulations of the Arctic atmosphere-ocean-sea ice-land system. Here, we provide...
